5P49V6975
Programmable clock generator with multiple outputs for high-performance computing, networking and industrial designs.
The 5P49V6975 is a Renesas programmable clock generator that produces multiple configurable output frequencies from a single reference, for high-performance consumer, networking, industrial, computing and data-communications applications, in a compact QFN package. It replaces several fixed oscillators with one device and provides the low-jitter clocks that high-speed interfaces and data converters require, and its configuration can be stored on-chip so the device starts up correctly. It is part of Renesas's broad timing portfolio, one of the widest in the industry, which spans programmable generators, buffers, jitter attenuators and synthesizers. Because jitter and phase noise affect the performance of the interfaces and converters a system depends on, the clock is often a decisive part of the signal chain, and the reference and the layout matter as much as the device. The choice between the timing devices follows from the number of outputs, the frequencies and the jitter the system tolerates. Every device is factory-traceable and ships with an import declaration, a certificate of origin and RoHS documentation. BeiLuo holds this part in regional stock and our FAE team supports clock configuration, reference and layout design.
FAE Professional Review
This is the clock generator we recommend for high-performance networking and computing designs that need several low-jitter clocks. It replaces fixed oscillators with one flexible device, and the on-chip configuration simplifies start-up. Keep the reference clean and the output traces controlled, and measure the jitter with the real load, because the layout and the reference decide the result.
